IMPHDVEMENT lili PBUTAECTSHG UNSLAKED LIME Alli) APPARATUS 'THERE-FUR.,

Specification forming part of Lett-ers Patent No. 118,680, datedSeptember 5, 1871.

To all whom 'it may concern:

Be it known that I, HENRY BISBING, of Bridgeton, county of Cumberland,State of New Jersey, have invented an Improvement in Protecting UnslakedLime and Apparatus lherefor, of', which the following isaspecificat-ion:

My invention consists of' a process of protect ing nuslaked lime from.the injurious effects of heu-t and moisture by inclosing it within adouble casing, between the walls of which is packed plaster of Paris orother equivalent protecting medium; andy my invention also consists ofa. casing having one or more compartments, `with double walls anddouble' doors, and by which the above process may be carried intoeffect, a-ll as fully described hereafter.

Figure 1 is a sectional perspective view of one form of1irometing-cash]5,,l by -which Amy invention may be carried into effect;Fig. 2, a longitudimil section of the same; 4and Fig. 3, a perspectiveview of a. casing with several compartments.

Lime, after having been burned and cooled, it' exposed to the air andheat of the sun, is very apt to fall or b'ccomc-slaked, owing to theab'- sorption of moisture. This is especially Vthe case inthe summerseason, and, as such dry sla-hed or fallen lime is absolutely worthlessas lime, thousands of' bushels are thus aunually'lost to bothmanufacturers and dealers. Lime is also canal-boats from the k'ilns tothe point or points of consumption, and when thus heated itis veryliable to fall or become slaked shortly after being removed from theboat, if' exposed to further heat and a damp atmosphere. The object ofmy whetherlarge or small, from the injurious effects of heat andmoisture and this I accomplish by incloning,r the lime within casings,chambers, or even buildings made with one or more compartments having'double walls a-nd double doors, the

of Pars, slaked lime, or other equivalent material which will absorb themoisture of the atmosphere and prevent the latter from gaining access tothe lime.

These protecting-casings may be made o'f; wood or other suitablematerial, and of any size, shape, and arrangement which will best suitthe wants of' the packer or dealer.

1n the drawing are represented two forms of cas-ings, both of which Ihave submitted to sel vere practical tests with the most satisfactoryresults.

The casingr shown` in Figs. 1 and 2 is constructed o f wood, of anoblong and rectangular shape, and has Vdouble' walls a andb, the .intenvening space c between which is packed with plaster 'of' Paris, slakedlime, or equivalent absorbent material." The casing is also raisedslightly above the ground by cross-pieces d, a-nd is provided at eachend with double sliding doors c c', the spaces between which are alsofilled with plast-er of.' Paris or its equivalent.

I have preserved lime in a ,ca-sing' constructed 'as above described forseveral months wit-hout having it undergo the slightest. appreciablechange. A

'lhe casing.,r illustrated in Fig. 3 1s constructed with severalseparate. compartn'ients, .1; w', &c.,

and is intended more especially for the use ot dealers, as thisarrangement enables all or ay portion ot' the lime to be removed fromone compartmentwithout exposing that contained inthe others.

I claim- 1. The protecting of unslaked lime from the injurious effectsof heat and moisture by iuclosiugzit within adoublc casing, between thewalls of whiclris packed plaster of Paris or other equivalent protectingmedium.

The within-described casing, having one or more compartments and doubledoors, substantially as set forth.

In testimony whereof I have signed my name to this specification in thescribing witnesses.
